Abstract (en)
[origin: EP0670630A1] The amplifier system includes an input transmission line, an output transmission line, a primary amplifier circuit, a backup amplifier circuit, a bypass circuit. An amplifier switching device is used for mutually exclusively connecting the primary amplifying circuit, the backup amplifying circuit and the bypass circuit between the input and output transmission lines. The system also incorporates a device for generating a primary failure signal in response to an abnormal current draw of the primary amplifier. The amplifier switching device includes a device for automatically disconnecting the primary amplifier from the input and output transmission lines in response to the primary failure signal.
